NUT-LOCK.

SPE CIFICATION forming part of Letters Patent No. 373,697, dated November 22, 185'?.

Application filed March 2, i887. Serial No. 229.413. (No model.)

T0 all whom it may concern:

Be itk nown that I, DAVID Sfr-EINER, a citizen of the United States, residing at Adamsburg, in the count-y of -Vestmoreland and State of Pennsylvania, have invented certain new and useful Improvements in Nnt-Locks5 and I do declare the following to be a full, clear, and eX- act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specication.

This invention relates to nnt-lQcks which have slides interposed between the sides of two adjacent nuts.

rllhe improvement consists in having a metallic washer clamped between the iish-plate and the nut, and having aportion ofthe washer extended up alongside the nut for a short distance and then bent at right angles to the edge of the nut and projected away from said nut a short distance, forminga lip, which is located at a distance from and approximately parallel with the iislrrail for holding the locking-slide between it and the tish-rail, as will be more fully hereinafter set forth, claimed, and shown in the drawings, in which- Fignrel is a perspective view of a railjoint embodying niy invention. Fig. 2 is a horizontal section on the line t x ot' Fig. l. Fig. 3 is a modification, and Fig. 4 is an end view of a rail of my invention.

The object of the invention is the production of a nut-lock which will be simple and can be applied and removed without requiring the attention of a skilled mechanic and which will be durable and easily managed.

The rail A, the {ish-plate B, andthe bolts C and nuts D are old and of well-known construction, and are shown simply as a means for carrying out my invention, which consists of the washer E, having a portion clamped between the nuts and the tish-plate, the portion e, extended up alongside the edge of the nut, and the portion e', projecting at right angles to the edge of the nut and approximately parallel with the sh-plate, and the locking-slide F, slipped in between the sides of two adjacent nuts and heldin place by the portions e', which 'will be designated as retaining-lips. Where there are more than two nuts to be locked, the intermediate nut or nuts will have the washer E.(see Fig. 8) extending in opposite directions beyond the sides of, up along the edges of, and at right angles to the nut forming retaininglips j' on each side of the nut.

In practice the washers may be made so as to be of sufficient bulk to withstand the action of the atmosphere; but for ordinary purposes sheet metal cut in desired form will answer. The washer is iirst placed upon the bolt; then thenutis placed in position and screwed home. If the washer is already shaped, the nut and the washer will turn together; but if the washer is left dat, the nut alone will turn, and when screwed up tight the free end of the washer is turned out anti over the locltingslide, which is placed in position, as will be readily understood. The lockingslide is held in position by the retaining'lips of the washers and is of sufficient length to rest upon the foot of the rail or the flange of the deh-plate.

I am aware that it is old to havea nut-locking device composed of a plate provided with a series of openings which are iitted over a corresponding` series of nuts for locking them and held in place by a bolt passed through it near one end and a nut mounted on said bolt and having said end folded and a wedge held in the fold for locking said nut. It is also old to have winged washers clamped between the base and the nuts and to have an apertured plate fitted over the nuts and the wings of the washer bent down upon the plate ou each side of the apertures for holding the platein position. Itis further old to have a slotted plate fitted over the nuts and held in place by straps of iron which are clamped in position at one end by the end nuts and have their free ends bent outward and over the ends of said plate. Such construction is not claimed, broadly, in that it is essentially different from mine, as specifically recited in the claims.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

l. The combination, with the two bolts, the nuts screwed thereon, and the washers mounted upon the bolts and heldin place bythe nuts, and provided with retaining-lips projected toward each other and at right angles to the edges of the nuts, of the locking-slide adapted IOO sides of and between the middle and end washers and heldin place by said retaining-lips, whereby one or both slides can beremoved or to be slipped down between the approximate edges ol' the nuts and held in place by the retaining-lips, substantially as described.

2. The combination,with the three bolts, the replaced, substantially as set forth. nuts, and the washers mounted upon the bolts l In testimony whereof I affix my signature in and held in place by the nuts, the end washers presence of two witnesses. having retaining -lips projected toward the middle washer, and themiddle washer having v DAVID STEINER' retaining-lips extended toward the end washl Witnessesz ers, substantially as shown, of the two inde- ALEX.
